intent:Qualification Failed

Include a few more examples in the nlu data. I had to add 4~5 examples, then the regex started working. Also, you have 6 digits in your training example but you’ve mentioned [0-9]{5}. And your second syntax is correct way of defining not the first.

If I give a n input of NPANXX invalid 1234907865, then I should not get any entities. But, it gives me the entities.
“entities”: [
{
“start”: 15,
“end”: 25,
“value”: “1234907865”,
“entity”: “regexp”,
“confidence”: 0.5930968739654005,
“extractor”: “ner_crf”
}
],
which is wrong.
